Answer:
(1) glycerophospholipids ⟶ (C) lipids with phosphate-containing head groups
(2) cerebrosides ⟶ (D) fatty acid linked through an amide bond to the sphingosine C(2)-amine
(3) gangliosides ⟶ (B) anionic sphingolipids containing one or more sialic acid residues
(4) sphingolipids ⟶ (A) built on sphingosine
Explanation:
1) Choline (Fig. 1) is a glycerophospholipid. It is a glycerol-based lipid with a phosphate-containing head group.
(2) Galactosylceramide (Fig. 2) is a cerebroside. It contains a fatty acid linked through an amide bond to the sphingosine C(2)-amine
(3) Gangliosides are glycosphingolipids that contain sialic acid. GQ1b (Fig. 3) is one of the most abundant gangliosides in the human brain. The carboxyl group of the sialic acid is in the ionic form.
(4) Sphingomyelin (Fig. 4) is a sphingolipid. It is based on sphingosine, with a phosphocholine head and a fatty acid chain.
1. Cells use glucose to make
energy.
2. Which of the following is broken down to provide the body with glucose?
simple sugars and starches
3. What makes essential fatty acids and essential amino acids different from ones that aren’t essential?
Nutrients that are essential cannot be made by the body, so they must be obtained from food.
4. A car is to gasoline as your body is to
food.
5. Starches are to simple sugars as proteins are to
fatty acids.
amino acids.
Answer:
No, se debe a la capacidad de evolucion genetica que tengan los seres vivos frente a los cambios amientales.
Explanation:
Algunos animales frente a cambios ambientales buscan desarrollar mutaciones geneticas que le confieran una cualidad fenotipica que los beneficie en ese medio, es decir como por ejemplo: picos mas largos, plumajes de diferentes cualidades, patas o dedos mas cortos, etc.
Si esta modificacion genetica es capaz de transmitirse a travez de los progenitores de la especie entonces se puede deducir que la especie evoluciono, por ende tiene una adaptacion exitosa y no depende de sus celulas sino del codigo genetico que estas contengan y si son capaces de transmitir dichos genes para poder asi heredar otras generaciones las cualidades fenotipicas ideales.
